FIELD: pulp-and-paper industry, in particular, equipment used in papermaking machine. ^ SUBSTANCE: detachable holder is mounted on papermaking machine equipped with cylinder positioned for rotation around axis extending transverse to machine, and squeegee moved to cylinder surface by means of holder extending in parallel with said axis. Holder is mounted on squeegee support and is provided with device providing for transverse movement of squeegee holder relative to squeegee support. Said device has guide attached to squeegee support and extending transverse to machine, and groove running in guide, lengthwise thereof. Groove has bottom, width extending between opposite sides, and top defined by projections protruding inward from said sides. Projections have inner edges spaced from one another so as to define slot arranged under squeegee holder and having width smaller than that of groove, plurality of hollow pins spaced from one another lengthwise of squeegee and extending downward from it through slot into groove, first and second independently rotating members mounted on said pins. First rotating members are located in slot and are sized to provide for contacting with inner edges of projections and second rotating members are located in groove and are sized to provide for contacting with lower edges of projections. ^ EFFECT: increased efficiency by reduced friction resistance in the process of withdrawal and replacement of squeegee. ^ 4 cl, 3 dwg |
